epistemological perspective, Ti leads one to trust only things that you understand first-hand for yourself, preferably through direct, hands-on interaction. You must see for yourself how a given thing or subject makes sense. Knowledge must emerge from the concrete reality itself, not from preconceived categories or criteria, and the search for knowledge must follow wherever logic and the subject matter lead, regardless of how people feel about it. As an ethical perspective, Ti leads you to do what is best for the system regardless of reward or gain or social conventions that define right and wrong behavior. For example, the sense of "natural law" that guides Clint Eastwood to do what needs doing in Old West towns regardless of the law.
(Si) tunes you in to the chaos, unpredictability, and unknowability of the concrete world, leading you to value whatever few signs you can find that have stable meaning. For example, the stripes of tabby cats might hold a particular meaning for you, and you might come to treasure that. As an epistemological perspective, Si leads you to view anything from outside a familiar context as dangerous and untrustworthy. You are in tune with the fact that nearly all possibilities lead to destruction. For example, if you're designing an airplane, nearly all combinations of the variables fail. Of the possible combinations of wingspan, wing placement, wing shape, fuselage shape, and so on, there is only a tiny subset that make an aerodynamically workable plane--and then only if you get a whole lot of other things just right, too. All of life is like that, only much more complicated. We live only in the small islands of the world that we've grown up with and are suited to us. And we can't possibly know why these small islands are relatively safe. As an ethical perspective, Si leads you to protect the integrity of the things and signs that we depend on. This usually takes the form of setting up barriers against the unpredictable. For example, saving for a rainy day (hardships come at unpredictable times) or inspecting buildings for fire safety (so people can trust that "being inside a building" is a sign of safety against the elements). Within these barriers, where all is trustworthy and familiar, we can survive and enjoy what is precious to us--for a while.
so do you think you're intp then? cuz of the Ti and Ne and Si?
